Grid Background

A procedural background/reference-grid surface built on @builtin::shaders.grid_bg. It draws grid lines over a black base colour (0.0, 0.0, 0.0) with full roughness (1.0) and no metallic response, rendered opaque with culling disabled (cull: none) and instancing enabled so it can back many objects at once.

Inputs

• colors.base_color (0.0, 0.0, 0.0, 1.0) — black backdrop behind the grid lines.
• floats.roughness (1.0) — fully diffuse, no highlights.
• render.cull (none) — visible from both faces.
• render.instancing (true) — supports instanced draws.
